RE: HTTP attack looking for /sumthin ?

Looks like a automated scan, looking for active web servers.  Are the IP's
sequential?  How about on Source?  are they sequentialized ports?

I have seen this on our servers, starting Oct 12 with 213.165.144.xxx 
(only one ip) and then again on the 15th from 194.236.60.xxx (also one 
ip) .

Each time they hit they sent 5 to 6 attempts within one second, all 
looking in the same place.

213.165.144.xxx - - [12/Oct/2002:05:40:01 -0500] "GET /sumthin HTTP/1.0" 
404 1086 "-" "-"
213.165.144.xxx - - [12/Oct/2002:05:40:01 -0500] "GET /sumthin HTTP/1.0" 
404 1086 "-" "-"
213.165.144.xxx - - [12/Oct/2002:05:40:01 -0500] "GET /sumthin HTTP/1.0" 
404 1086 "-" "-"
213.165.144.xxx - - [12/Oct/2002:05:40:01 -0500] "GET /sumthin HTTP/1.0" 
404 1086 "-" "-"
213.165.144.xxx - - [12/Oct/2002:05:40:01 -0500] "GET /sumthin HTTP/1.0" 
404 1086 "-" "-"
(6 times in all.)

All logs look identical to your post.
What do we have here ?

cheers,
cory
